Chemical dangers
 

Occupational exposure limits
MAK: Carcinogen category: 1; Germ cell mutagen group: 3A; (DFG 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation of dust and by ingestion. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the gastrointestinal tract and nervous system. 

Effects of long-term or repeated exposure
The substance may have effects on the gastrointestinal tract, nervous system, kidneys, liver and blood. This substance is carcinogenic to humans. May cause reproductive toxicity in humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
